They have a slightly larger overall body size than the house mouse. The New Holland mouse's habitat can generally be found among woodlands, open heathlands and dry forests, grasslands, and vegetated sand dunes. They inhabit these areas in search of food and mating.
The density of these mice is often great in regions with heath vegetation that regenerates every two to three years after a fire, and also in areas with a great diversity of flora. Their diet is omnivorous, consisting of plants and fungi as well as fruit.
Males become sexually mature at around 20 weeks, whereas females mature at 13 weeks. Their breeding season generally occurs from winter to early spring and sometimes autumn in the north region and from spring to summer in the southern region.
Their population has been threatened by various factors, including loss of habitat, fire, invasive predators, along with climate degradation. The diet of these mice consists of seeds, small invertebrates.
These threatened native rodent habitat has been distributed across regions like Victoria, Tasmania, Queensland, and New South Wales. Protection has been provided to these rodents populations to avoid their extinction.
